- Incorrect installation, adjustment, changes to, or
maintenance of this refrigerator can cause personal
injury, property damage, or both.

any work on the propane gas supply system. Do not
use an open flame to examine the gas supply piping
or fittings for leaks.
- To avoid possible propane gas leaks, always use two
wrenches to tighten or loosen the gas supply line
connections.
